Product details
Overview
S29GL128P90FAIR12 from Cypress Semiconductor is a 128 Mbit (16 MB) single-supply 3.0 V page-mode Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 90 ns random access time, 25 ns page access time, uniform 64 Kword (128 Kbyte) sector architecture (128 sectors), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.
For engineers reviewing the S29GL128P90FAIR12 datasheet, S29GL128P90FAIR12 pinout, S29GL128P90FAIR12 application, or S29GL128P90FAIR12 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (32-word/64-byte burst), secured silicon sector with factory-programmable ESN, and CFI-compliant interface for host controller compatibility.
Technical Context
This device operates exclusively in single 3.0 V supply mode (2.7–3.6 V), with all I/O levels dynamically referenced to VIO - enabling interoperability across mixed-voltage microcontroller buses. Its architecture supports byte/word configuration via BYTE# input and integrates hardware reset (RESET#) and Ready/Busy# status signaling for deterministic system-level timing control.
The S29GL128P implements advanced sector protection using both persistent lock bits and password-based methods, plus WP#/ACC dual-function pin for hardware write protection and VHH-accelerated programming during production. Sector erase time is fixed at 0.5 s per 64 Kword sector, with program times reduced to 13.5 µs/word using VHH acceleration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) organized as 2,097,152 × 8 or 1,048,576 × 16 - directly maps to standard boot ROM address spaces in ARM Cortex-M and RISC-V SoCs. |
| Access Time | 90 ns random access (Regulated VCC); 25 ns page access - enables real-time instruction fetch without wait states in 20–25 MHz bus systems. |
| Write Buffer Size | 32 words / 64 bytes per operation - reduces effective programming time by >60% vs. single-word writes in firmware update routines. |
| Erase Endurance | 100,000 cycles per sector - supports field firmware upgrades over 10+ years in industrial gateways and PLCs. |
| Data Retention | 20 years typical - ensures long-term reliability in unpowered storage for medical and aerospace black-box log retention. |
| VersatileI/O Range | VIO = 1.65 V to VCC (2.7–3.6 V) - eliminates level shifters when interfacing with 1.8 V or 3.3 V host processors. |
| Operating Temp | –40°C to +85°C (Industrial grade) - validated for deployment in outdoor telecom base stations and automotive ECUs. |
Pinout & Package
Package: 64-ball Fortified BGA (LAA064), 11 × 13 mm, 1.0 mm pitch, Pb-free (RoHS compliant). Pinout conforms to standard S29GL-P BGA layout with dedicated VIO, RESET#, RY/BY#, and WP#/ACC pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A22–A0 | Address Inputs | 23-bit address bus (A22–A0) selects one of 128 sectors; A22 is MSB for 128 Mbit density. |
| DQ15/A-1 | Bi-directional Data / LSB Address | In word mode: DQ15 carries data; in byte mode: functions as A-1 for 8-bit addressing alignment. |
| BYTE# | Bus Width Configuration | Pull-low enables 8-bit DQ0–DQ7 operation; pull-high enables full 16-bit DQ0–DQ15 data path. |
| WP#/ACC | Write Protect / Acceleration | At VIL: locks top/bottom sector; at VHH (12 V): enables unlock-bypass programming for high-throughput manufacturing. |
| RY/BY# | Operation Status Output | Active-low open-drain signal indicates active erase/program; used for polling or interrupt-driven firmware updates. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with 8-word electronic serial number - provides immutable device identity for secure boot and anti-cloning. |
| Uniform Sector Architecture | 128 identical 64 Kword sectors - simplifies flash translation layer (FTL) design and enables deterministic wear leveling in embedded Linux rootfs partitions. |
| Suspend/Resume Commands | Interrupts ongoing erase or program operations to service higher-priority reads - critical for real-time HMI and diagnostics logging. |
| CFI Compliance | Standard Common Flash Interface descriptor table at known offset - allows automatic detection and parameter loading by U-Boot, BIOS, and RTOS bootloaders. |
| Automatic Sleep Mode | Enters <1 µA standby current after 100 µs of bus inactivity - extends battery life in portable test equipment and edge sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar page-mode Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29GL128FPTI-90G | 90 nm process, same 128 Mbit density and 90 ns access, but lacks VersatileI/O - fixed 3.3 V I/O only. | Requires external level shifting when interfacing with 1.8 V SoCs; no VIO flexibility for mixed-voltage designs. | Select when cost sensitivity outweighs I/O voltage adaptability and VIO is not required. |
| S29GL128S90TFI020 | Same Cypress S29GL family, 64-ball BGA, but uses 65 nm Eclipse process - lower active current (40 mA vs. 50 mA), same 90 ns timing. | Improved power efficiency in battery-backed applications; identical pinout and command set - drop-in replacement. | Select for new designs prioritizing lower power consumption while retaining full software and hardware compatibility. |
Compared with MX29GL128FPTI-90G, S29GL128P90FAIR12 offers VIO-driven voltage adaptability critical for heterogeneous SoC interfaces; versus S29GL128S90TFI020, it trades slightly higher active current for mature 90 nm process stability and broader industrial qualification history.

FAQ
What is the function of the WP#/ACC pin on S29GL128P90FAIR12?
The WP#/ACC pin serves dual roles: at VIL (≤0.8 V), it protects the highest or lowest sector from accidental program/erase; at VHH (11.5–12.5 V), it enables unlock-bypass programming mode, accelerating write throughput by eliminating command overhead. It features an internal pull-up, defaulting to VIH when unconnected.
Does S29GL128P90FAIR12 support byte-wide data access?
Yes - asserting BYTE# low configures the device for 8-bit operation, activating only DQ0–DQ7 and repurposing DQ15/A-1 as the LSB address input (A-1). This enables direct connection to 8-bit microcontrollers without data bus demultiplexing.
How does the Secured Silicon Sector enhance system security?
The 128-word Secured Silicon Sector contains a factory-programmable 8-word Electronic Serial Number (ESN) that can be permanently locked. This provides a tamper-resistant hardware identity used for secure boot verification, firmware signature binding, and anti-counterfeiting in certified medical and defense systems.
Can S29GL128P90FAIR12 be used with a 1.8 V host processor?
Yes - with VIO supplied at 1.8 V and VCC at 3.0–3.6 V, all address, control, and data signals operate at 1.8 V logic levels. This eliminates external level shifters when interfacing with modern low-voltage MCUs like STM32U5 or NXP i.MX RT10xx series.
